The tissue was placed in a nonmetallic container. Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured. 4) The complex relative permittivity ε ’ can be calculated from the below equation (Pournaropoulos and Misra): where Y is the admittance of the probe in contact with the sample, the primed and unprimed coordinates refer to source and observation points, respectively, ,  is the angular frequency, and .

All data rates were investigated to determine the worst case configuration. For the following out of band conducted spurious emissions plots, the EUT was investigated in all available data rates for “b”, “g”, “n” modes. The worst case spurious emissions for the 2.4GHz band were found while transmitting in “b” mode at 1 Mbps and are shown in the plots below. The limit for out-of-band spurious emissions at the band edge is 20dB below the fundamental emission level, as determined from the in-band power measurement of the DTS channel performed in a 100kHz bandwidth per the procedure in Section 11.11 of ANSI C63.10-2020 and KDB 558074 D01 v05r02. Test Procedure Used ANSI C63.10-2020 – Subclause 11.11.3 KDB 558074 D01 v05r02 – Section 8.5 Test Settings 1. Start frequency was set to 30MHz and stop frequency was set to 25GHz (separated into two plots per channel) 2. RBW = 1MHz 3. VBW = 3MHz 4. Detector = Peak 5. Trace mode = max hold 6. Sweep time = auto couple 7. The trace was allowed to stabilize Test Setup The EUT and measurement equipment were set up as shown in the diagram below. Figure 7-5.

RBW was set to 1MHz rather than 100kHz in order to increase the measurement speed. 2. The display line shown in the following plots denotes the limit at 20dB below the fundamental emission level measured in a 100kHz bandwidth. However, since the traces in the following plots are measured with a …
